DETAILED DESCRIPTION

[0032] My first embodiment of my game hunting video camera invention, in its non-operational mode, is illustrated in FIG. 1. The video camera is shown having a main camera body 10, a camera weather cover 12, a camera base 16, a liquid crystal display housing member 18, a liquid crystal display weather shield 20, a camera mount member 14, a zoom in button 22 and a zoom out button 24. The video camera in its operational mode is illustrated in FIG. 2. FIG. 3 illustrates the front side of the camera base 16. The front side of the camera base 16 contains the lense 26 of the camera, a circular recess portion 34, a front facing microphone 28 for recording the sounds produced by the game and normally closed SPDT push button camera record switch 30 that turns the video camera on and off.

[0033] An liquid crystal display housing member 18 is attached by hinges 11 to the camera base 16. When the video camera is in its non-operational transportation mode, the liquid crystal display housing member 18 is rotated on its hinges 11 so it is in front of the camera base 10 as illustrated in FIG. 1. When the liquid crystal display housing member 18 is in this position the normally closed camera record switch 30 is open and the video camera is off. The liquid crystal display housing member 18 is held in this position by a protruding circular semi pliable seal 32 that has one side solidly connected to the liquid crystal display housing member 18 as illustrated in FIG. 3. The other side of the circular semi pliable seal 32 is tightly received in the circular recess 34 located in front of the camera base 16. This seal connection not only keeps the liquid crystal display housing member 18 in the non-operational position, it also protects the lense 26 when the video camera is turned off. This is an important feature because the video camera is likely to be exposed to harsh environments as a hunter pursues his or her game. My design not only protects the lense 26 from scratches, as the hunter makes his or her way through the woods or brush, it also protects the lense from weather conditions.

[0034] When the hunter sees game he or she simply rotates the liquid crystal display housing member 18 about its hinges 11. This action closes the camera record switch 30 completing the circuit that starts the video camera recording. The ease and speed in which the video camera is started is very important in a hunting situation because a hunter may not have much time to react when the game is sighted. My design minimizes the time needed to get the video camera recording. In addition, the hinges 11 are tightly bound so that the liquid crystal display housing member 18 is put in a position by the operator it will stay there until the operator once again acts upon it.

[0035] The back side of the camera base 16 and the liquid crystal display housing member 18 is illustrated in FIG. 4. A rear microphone 19 is placed on the back side of the camera base 16 for recording the sounds produced by the hunter. The back side of the camera base 16 also has a indicator light 23 that lights up when the video camera is recording. A liquid crystal display 36 is encased in the back side of the liquid crystal display housing member 18. The operation controls of the camera are also placed in the back side of the liquid crystal display housing member 18 around the liquid crystal display 36. The operating controls are common in the art of video cameras and may include the following: a menu control 38, a liquid crystal display brightness control 39, a speaker control 40, an on/off record switch 42, a play control 44, a search control 46, a menu select dial 48, a battery charge connect port 50, a s-video terminal 52, a audio out port 54 and a video out port 56.

[0036] A weather shield is connected by pivots 27 on the back side of the liquid crystal display housing member 18 as illustrated in FIG. 4. The liquid crystal display 36 is activated when the liquid crystal display weather shield 20 is rotated in an upward direction. This action closes the normally closed SPST push button liquid crystal display switch 25 activating the liquid crystal display 36. Besides controlling the liquid crystal display switch 25 the liquid crystal display weather shields also shields the liquid crystal display 36 from the weather. In addition, the liquid crystal display weather shield 20 has a liquid crystal display weather shield tab portion 21 that protrudes out beyond the body of the liquid crystal display housing member 18 as illustrated in FIG. 3. This tab portion allows the hunter to quickly flip the liquid crystal display weather shield 20 up to activate the liquid crystal display 36. The pivots 27 are also tightly bound so that when the operator puts the weather shield in a position it will remain there until the operator once again acts upon it.

[0037] The circuit that turns the video recorder and the liquid crystal display 36 on and off is an important feature of my invention and is illustrated in FIG. 7. A simplified circuit is shown having a battery source 60, a video recorder portion, a liquid crystal display portion, a relay 68, the camera record switch 30, the on/off record switch 42, the liquid crystal display switch 25, an upper wire 72 and a lower wire 74. The circuit is shown, having the liquid crystal display housing member 18 rotated in front of, and attached to, the camera base 16. Accordingly, the normally closed camera recorder switch 30 is in its open position 71. The circuit is also shown having the on/off switch 42 in its open position 75. If this situation occurs, the relay 68 automatically acts on the on/off record switch 42 switching it to the closed position 77. This ensures that every time the liquid crystal display housing member is rotated to the camera's operational position, the camera starts recording automatically. The operator will not have to waste time manually pushing the on/off record switch 42 on the liquid crystal display housing member 18 to get it in the right position. When the camera recorder switch 30 is in its closed position 73 and the on/off record switch 42 in its closed position 77, the circuit is complete and the video camera starts recording. The liquid crystal display 36 is turned on when the liquid crystal display switch 25 is closed. This occurs when the liquid crystal display weather shield 20 is flipped up.

[0038] My video camera has a cylindrical weather cover 12 that screws onto the main camera base 10. This is illustrated in FIG. 5. As the weather cover 12 is screwed onto the main camera body 10 it comes in contact with a rubber ring 41 thereby sealing the internal components from the weather. The weather cover 12 also provides easy access to the cassette holder 58 and the battery 60. The operator simply has to unscrew the weather cover 12 to put in a video cassette or replace the battery 60. The main camera body 10 is also cylindrical in shape and houses the main components of a standard analog or digital video camera recorder known in the art. These components are illustrated in FIG. 6.

[0039] The second embodiment of my invention is illustrated in FIG. 8. Instead of the operator manually moving the liquid crystal display housing member 18 and the liquid crystal display weather shield 20 to activate the video recorder and the liquid crystal display 36 respectively, this embodiment uses electronic switches. FIG. 8 illustrates the video camera in the non-operational mode. In addition to the zoom in button 22 and the zoom out button 24, the main camera body 10 also has an on/off button 76. When the on/off button 76 is activated the liquid crystal display housing member 18 slides out from the camera base 16 as illustrated in FIG. 9. As in the first embodiment, the liquid crystal display housing member 18 covers and protects the lense 26 when the camera is in its non-operational mode. When the liquid crystal display housing member 18 is fully extended, as illustrated in FIG. 10, the camera automatically starts recording and the liquid crystal display 36 is activated.

[0040] This embodiment has a remote port hookup 86 on the camera base 16. A remote pad 78 having a zoom in the button 80, a zoom out button 82 and an on/off button 84 can be attached to the remote port hookup 86, the remote pad 78 becomes operational. This design allows the operator to place the camera controls in a convenient location for optimal efficiency, like the forearm 100 of a firearm or the riser 104 of a bow.

[0041] Although, there are equivalent ways, common in the art, to control the movement of the liquid crystal display housing member 18, my preferred method is illustrated in FIG. 11. The liquid crystal display housing motor 81 has threaded shaft 83. The liquid crystal display housing member 18 has an internally threaded insert 85 that is threadably engaged with the threaded shaft 83 of the liquid crystal display housing motor 81. An “H” switch circuit controls the direction that the threaded shaft rotates. When the threaded shaft 83 rotates clockwise the liquid crystal display housing member 18 sides into the camera base 16. When the threaded shaft 83 rotates counter clockwise the liquid crystal display housing member 18 sides out of the camera base 16. The use of this system is common in the art and an example of an “H” switch circuit can be found in U.S. Pat. No. 4,454,454 issued to Valentine entitled Mosfet “H” Switch Circuit for a DC motor. In addition, a block diagram of the system is illustrated in FIG. 12.

[0042] A bracket that mounts to a weapon is illustrated in FIG. 13. The upper mount member 91 has a number of screw holes 97. The lower mount member 92 has the same number of threaded screw holes 99. A foam rubber insert 93 covers the inner surface of the upper mount member 91 and the inner surface of the lower mount member 92 to protect the surface of what the mounting bracket is being mounted to. The bracket mounted to a barrel 98 of a firearm is illustrated in FIG. 14. The upper mount member 91 is placed over the top of the barrel 98 of the firearm. The lower mount member 92 is placed under the barrel 98. The screw holes 97 in the upper mount member 91 are then lined up with the threaded screw holes 99 in the lower mount member 92, securing the mounting bracket to the weapon. In addition, the thickness of the foam rubber insert 93 can be changed to accommodate different size barrels 98.

[0043] As FIG. 14. illustrates, the video camera is attached to the mounting bracket by sliding the camera mount member 14 into the track of the lower mount member 92. When the camera mount member 14 is positioned far enough into the track of the lower mount member 92 it is locked into place. This is to ensure that the camera will not inadvertently fall off the weapon. The mechanism that locks the camera into place is illustrated in FIGS. 15, 16 & 17. A pair of biasing springs 107 are inserted into cavities 111 in the camera mount member 14. A pair of fastening buttons 105 are then inserted into the cavities 111 engaging the biasing springs 107. The fastening buttons 105 are held in place by a pair of camera mount member plates 103. The camera mount member plates 103 have circular holes that allow the fastening buttons 105 to protrude through them from the force of the biasing spring 107. The camera mount member plates 103 are secured by the camera mount plate screws 101 being screwed into the threaded holes 109 in the camera mount member 14.

[0044] A pair of release push buttons 115 are inserted into the push button cavities 116 in the lower mount member 92. The release push buttons 115 are held in place by the mount member plates 114. The mount member plates 114 are secured to the lower mount member 92 by the mount member plates screws 113 being screwed into the threaded screw holes 117. The mount member plates 114 have circular holes in them that are large enough for the fastening buttons 105 to fit through.

[0045]FIG. 16 illustrates how the camera mount member 14 locks into place with the lower mount member 92. As the camera mount member 14 slides along the track in the lower mount member 92, the biasing springs 107 assert an outward pressure on the fasting buttons 105. When the fasting buttons 105 encounter the holes in the mount member plates 114 they are forced into them. This action locks the video camera on the mount system. To remove the camera the operator simply presses in on the release push buttons 115. This action forces the fastening buttons 105 out of the holes in the mount member plates 114. This illustrated in FIG. 17. The camera will then slide off the mount effortlessly. Having this simple method of removing the camera is important to the invention because it allows, without undue delay, the use of the camera without it being attached to a weapon.

[0046] The first embodiment of the video camera mounted to the barrel 98 of a firearm is illustrated in FIG. 18. The firearm is shown having a barrel 98 and a forearm 100. One reason for the cylindrical design of the camera body is so it is natural for the operator to use the body of the video camera as he or she would the forearm 100 of the firearm. If the operator does this, his or her thumb will be in a natural position to operate the zoom in button 22 and the zoom out button 24 with little effort or movement. In addition, the remote pad 78 in my second embodiment can be attached to the forearm 100 of the firearm by Velcro, or by some similar fashion, for ease of operation.

[0047] The first embodiment of my invention mounted to a bow is illustrated in FIG. 19. The bow is shown having a riser 104, a flexible bow element 106, a cable guard 110, bow string 112, an internally threaded metal insert 108 is shown having the counter weight bar 102 threadably attached. A counter weight bar 102 is used to stabilize the bow when the bow string 112 is drawn back. The mounting bracket is attached to the counter weight bar 102 the same way it is attached to the barrel 98 of a firearm. In addition, the thickness of the foam rubber insert 93 in the mounting bracket can be changed to accommodate the diameter of the counter weight bar 102. Moreover, the remote pad 78 in my second embodiment can be attached to the riser 104 of the bow by Velcro, or by some similar fashion, for ease of operation.
